Title: Improvements in or relating to apparatus for machining work pieces
IPC: G04D3/00
Filed: 1941-08-21
Abstract: 553,300. Work-holding devices. RYFFE, R., and GOLDSCHMIDT, J Aug. 21, 1941, No. 10677. [Class 83 (iii)] In apparatus for machining precision work such as templates for producing plates and bridges for clockwork, a rotatable disc has mounted thereon a carrier 8 which is angularly adjustable about the axis of disc 1 and which carries compound slides moved by measuring devices, the upper slide being arranged to support the work. The disc 1 is carried on a spindle 2 mounted in a bearing 3 adjustably fixed to a lathe bed 4, the spindle being drivable from the lathe headstock by a driver 6. The carrier 8 is adjustably mounted on the disc 1 in a groove 10 and is clamped by eccentric bolts, the angular position being read by a scale. The disc 1 may be locked to the bearing 3 in a datum position by a bolt 12. The carrier 8 carries compound slides 14, 16, movable in mutually perpendicular directions by precision screws 15, 17 having micrometer heads coacting with vernier devices 19, 20 respectively. The top slide 16 carries a plate 21 to which the work is secured. The precision screws are associated with correction rules 22, 23 profiled according to the pitch irregularities. The vernier disc 19 is connected to a feeler 25, which slides along rule 22 when slide 14 moves, and imparts angular adjustment to the vernier disc. The disc 20 is similarly controlled by the rule 23. When the disc 1 is locked and the carrier 8 set to zero the lower slide 14 moves horizontally and points on the work may be set out by co-ordinates and the disc 1 subsequently rotated for drilling holes at predetermined points or dividing operations may be effected by angular adjustment of the part 8 with the disc 1 locked.

Title: Air cooles cooling tower
IPC: F28F25/12
Filed: 1978-03-17
Abstract: The suction-ventilated wet cooling tower (1) has an internal cooling fitting (2) consisting of scrubbing surfaces, a water feeding device (3) arranged above the internal cooling fitting (2), an axial ventilator (5) arranged in the upper part of the wet cooling tower (1), and a receiving basin (6), located in the lower part, for recooled water. The wet cooling tower (1) further has a square cross-section with two rectangular suction openings (7), which are arranged in opposite walls and in which plate-shaped louvre elements (8) clamped in bows (11) are suspended spaced apart and in a pendulum-like fashion from bearing rods (12). In the rest position, open gaps are present between the individual louvre elements (8). In the working state, air is sucked through the cooling tower (1) by the ventilator (5) in a countercurrent with respect to the water. In this case, the louvre elements (8) are raised by the suction air flowing through, and the air inlet cross-section is enlarged. The advantage of the device consists in an automatic enlargement or reduction in the air inlet cross-section, depending on the flow direction and flow rate of the air, without a mechanical drive device. Moreover, such an air inlet louvre releases a sufficiently large air inlet cross-section even in its position of rest. <IMAGE>

Title: Improvements in level indicating apparatus for liquid containers
IPC: G01F23/50
Filed: 1925-04-24
Abstract: 245,649. Girardet, J. April 24, 1925. Indicators actuated by floats. - In a liquid level indicator, a float slides on a vertical guide which can be rotated from a distance by Bowden mechanism. The amount of rotation is determined by contact of the float with a fixed helical surrounding rib, and therefore depends on the level of the float. A perforated cylinder 1 having an internal helical guide bar 1<a> is immersed in the liquid, and a float 2 slides freely on a guide bar 3 of angular cross section. If the float and guide bar 3 are rotated, the angle of rotation is determined by contact of a finger 4, carried by the float, against the helical guide 1<a>, and such angle will vary with the level. The guide 3 is rotated by a Bowden transmission device 9<b>, the two ends of the cable being secured to pulleys 9, 10, the latter carrying an indicating pointer. The pulley 10 has a second groove in which is secured a cable issuing from the casing at 13 and terminating in a knob 14 which is pulled to actuate the mechanism to rotate the float. The rotation of the float 2 before it is stopped by the guide 1<a> is therefore indicated by the pointer. The Bowden wire is actuated against the resistance of springs 7 and 15 at both ends, whereby the tractive effort required when there are bends in the cable, is less than if the spring is situated at the further end only.

Title: Improvements relating to cycle and like variable speed driving mechanisms
IPC: B62M11/14
Filed: 1945-05-01
Abstract: 591,678. Variable-speed gearing. RAVEN, W. H., WILKIE, W., and WADE, Ltd., C. G. May 1, 1945, No. 11010. [Class 80 (ii)] A variable-speed gear for a cycle provides three ratios by combinations of two pawl and ratchet mechanisms and one epicyclic gear train. A cruciform shape coupling member n moved by. rod o is slidably mounted on a fixed spindle b to which a sun wheel a is secured. To drive the hub shell c at a higher speed than the sprocket k, the coupling member is held in engagement with pegs s of planet carrier d by a spring r. Drive from the sprocket is transmitted through a slotted driving member i to the coupling n, and thence through the members a, d, e, to an annulus h connected to the hub shell c through pawls t and ratchet u. The speed of shell c being greater than carrier d, pawls f are overrun by ratchet g. For direct drive, coupling n is pulled to the right and engages with the shoulders v of pawls t, Fig. 3, drive being transmitted from the driving member i through coupling n, pawls t and ratchet u to the hub shell c. Further movement of the coupling member to the right allows it to slide under the ends y of pawls t and hold them out of engagement. In this case a decrease in speed is obtained, the drive being from coupling n through pawls t to annulus h and thence from carrier d to pawls f and ratchet g to the hub shell c.

Title: Improvements in apparatus for recording and reproducing sound
IPC: G11B3/20
Filed: 1924-05-05
Abstract: 215,396. Kramer, E. May 3, 1923, [Convention date]. Sound-boxes, arranging and supporting; tonearm joints.-In a sound recording and reproducing machine. two sound-boxes, one, 17, for recording and the other, 18, for reproducing, are fixed on a sleeve 9 which is movably mounted on a tube 4 jointed to the tone-arm 1. The tube 4 is closed at one end and has a single lateral aperture 16 for the passage of sound to or from one of the sound-boxes, according to which is in operation. The sleeve has two sound-apertures 19, 20, one for each sound-box, and is rotatable upon the tube 4, so that when one sound-box is in the operative position (e.g. as shown, the recorder 17) the aperture pertaining thereto in the sleeve registers with the hole 16, while the opening communicating with the other sound-box (20, as shown) is closed by the wall of the tube 4. The tube 4 is pivoted on a vertical pin 5 in a socket 2, which is itsellf mounted on a horizontal pivot-pin 3 in the end of the tone-arm 1. A- spring 25 may be arranged as shown to counterbalance partially the weight of the sound-boxes. Arranged between the ends of the parts 4, 9 is a spring 21, which pulls the end 22 of the sleeve into abutment against the adjacent end of the member 2 when the recording sound-box is in the operative position as shown. Lateral movement of the sound-box about the pivot 5 is thus prevented. When, however, the sleeve 9 has been rotated through 180‹, by means of a handle 10, to bring the reproducer 18 into action, the ends 11, 12 of the member 10 engage in recesses 14 in the end of the tube 4, thus limiting the inward travel of the sleeve caused by the spring 21. The end 22 of the sleeve is then opposite a recess 8 in the tube 2, so that the reproducing sound-box is free to swing about the vertical pivot 5 as well as the horizontal pivot 3.
